| (The Bing Cherry color looks more like rootbeer to me !) Russ finally found the problem to his barely-noticeable spongy brake pedal. He pulled apart the rear caliper and found that a piston had a minute crack in the face. Upon examination of another piston, he found yet another hole ! It appears that there is a flaw in the bar stock used to machine these pistons, causing a very very tiny hole to develop. After pressing in new pistons he bled the system, then went to work on a old U-Joint. |
| Left, Tony Harvey had rebuilt the left rear axel at the last tech session, so here he is buried in the repair of the right rear axel. |

| When Terry changed the fluid in his ZF, a bolt head fell out ! He stuck his finger in and felt around to find another bolt head. Both of these ring gear bolt heads were ROUND ! Meaning they had been spinning freely inside the case for a LONG time. Further inspection reveal ALL 10 BOLTS had broken, and the heads had been �polished and rounded�. How long ? Who knows. But at least one caught the attention of the gear, and was flung into or almost thru the case, cracking it. It could have been much worse, a totally trashed ZF, thus the smile on Terry�s face. |

| Several carburetor rebuilds were accomplished, while other cars lined up for the hoist to receive some A/C work, and Roger was busy cutting and welding much of the morning. |
 |
| Although the intended focus of this event was on A/C systems, with all the swinging going on, it could have been called �Hammer Day�. As one commented, way too much hammer was needed today. And sadly so. After finishing his brake caliper rebuild, Russ, and a couple of others, including Curt Hall installed new u-joints. By the end of the day, there was a pile of red (from rust) needle bearings. |

| The blue-handle pliers are just holding the vise from turning, while the hammer punches thru the old U-Joint. Above, the old joint apart, and right the new joint, the owner displays the new snap-rings versus the old style retaining clips. |
